Lithobates tarahumarae Tarahumara Frog
The genus Lithobates was split from Rana by Frost et al in 2006. This has been a controversial change ever since, and many authorities continue to use Rana.

Matt Cage pointed out a spot where the road bridged a small river as a likely location for Tarahumara Frogs, which he had seen on previous trips. Andrew DuBois and I had not previously encountered this species, so while Matt stood guard over the car, we scrambled down the steep hillsides and prowled the water's edges to find a few individuals.

The range of this species includes a few isolated spots in southern Arizona, but I had failed to find any there the few times I'd been in their habitat.
